It is the chocolate fudge you can's seem to wipe off from your ass hair after a huge crap. It gets crusty when it drys and hurts like a bitch when you wish to clean it off.
Damn i got crusty shit hair. I'm going to the toilet to pull some ass hairs out. Wont' be a sec.
it's when your mom craps on you while giving birth and since some baby's dont have hair when you're born your mom will think it's your hair for a while
After you take a deuce and don't wipe you ass properly you have a tendency to create shit crust. This is most noticed when excersizing, you have a burning sensation in the poo hole region. Also caused by having wet farts due to spicy foods.
Dude, I can't keep up this shit crust has lit my ass hole on fire.
